This is not the point. Point is that selling copies is thing of a past, as in today's digital age anyone can create a copy of almost anything, with as little effort as pressing a few buttons. The best way to avoid piracy of this kind is to sell not a copy but a service. Take world of warcraft for example - blizzard don't give a damn how much you copy it, because they don't sell a copy to you, they sell a service - user account with access to game world and your "save games". And don't tell me that this is different because you cant play it offline, major principle stays the same: service, not a copy.
